. 1nents in Attachments for Shocking-Machines, of which the following is the specification.

Our invention relates to shocking machines ada'pted for use with harvesters or binding machines of the ordinary form, the shocker being adapted to be connected to the binder at the side adjoining the binder deck so that the sheaves discharged from the binder will fall on the shocking machine.

Our invention has for its object to produce a sheaf receiving cradle to receive thesheaves thrown down from the binder deck and automatically deposit them in a shock forming basket, it being understood thatthe shocking machine is of theform which has a frame carrying a pivotally supported shock forming basket into which the sheaves have to be transferred after leaving the binder deck.

It consists essentially in a swinging arm capableof lateral displacement having a sheaf receivingcradle at the end thereof, said arm being suitably mounted on the shocking machine frame, means for operating or swinging the ariif, means for alternately displacing the arm laterally to the right and left, and means for grasping or tightening on the sheaf carried by the cradle when the arm is swung, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 IS a plan view of a shocking machine equipped with our invention part of the binding machine being shown in dotted outline. Fig. 2 is an enlarged detailed side elevation of the arm operating and deflecting means. Fig. 3 is an enlarged detailed side elevation of the arm, the cradle, and the standard carrying the arm. Fig. 4 is a vertical sectional view through the arm, the section being taken in the plane denoted by the line X X Fig. 3.

In the drawings like-characters of reference indicate corresponding parts in each figure.

1 represents the shocker frame which is if formed from longitudinal members 2 2' and transverse members 3, said frame being supported rearwardly by caster wheels 4 and forwardly by a carriage wheel 5 mounted at the end of a shaft 6 which is secured to the binder frame 7 at 8.

9 represents the binder master wheel and 10 the main shaft of the binder on which the aforesaid wheel is mounted.

11 represents the binder deck from which the sheaves are delivered to the shocking machine.

12 is .a. box like platform secured cen trally in the shocking machine frame in any convenient manner such frame being positioned so that it will receive the sheaves thrown down from the 'binderQ 13 is a converging basket'pivotally supported from the rear endof the longitudinal members 2, 2, the large or butt end of the basket being directed rearwardly so that when it is overturned the sheaves collected therein in the form of a shock will be thrown butts down on the ground. The basket .is supplied with a longitudinally di rected divider 14 which forms an open centor for the shock. The forward or head end of the basket 15 overhangs the rear end of the platform 12.

The parts as already described form no part of our present invention but are herein described 50 as to bring out more clearly the operation of the device which we claim.

A detailed description of the foregoing parts has not been given for the reason that they have already been fully described in a v prior application, filed the 12th day of November, 1909, under Serial No. 5277 i5.

In the the former application the sheaves delivered from the binder were thrown down directly shocking machine as described in on to the platform and an attendant sitting on the platform grasped the sheaves and placed them in the basket to either side of the divider. This is a laborious anwekpensive manner of operating and the present invention has for its object the substitution of an automatically operated device which will do away with the necessity of an attendant on the machine to place thesheaves' in the basket. v

Rearw-ardly to the platform we have selot cured two standards 16 and 17 which are formed with hearings to receive a cross shaft 18 which has'permanently secur'edto its inner end a gear wheel 19 and crank wheel 20 and carries at its outer end a disk wheel 21. The standard 17 has a partial gear or quadrant 22 mounted thereon which meshes with the gear wheel 19'such quadrant being supplied with a downwardly extending arm 23 to which is connected a drive link 24 fastened at its free end to a part shortly to be referred to.

25 is a shaft having an enlarged or flared end which is coupled directly to the shaft 10 of the binder. The shaft 25extends over the shocking machine frame and is provided at its end with a loose disk wheel 26 which carries the driven member 27 of a clutch which is engageable with a slidable driving member 28 feathered on the shaft. driving member. is held into engagement with the driven member by means of a spring 29 and can be retracted therefrom by the action of a link 30, the action of which is controlled by the operator on the binding machine, as will readily be understood. The free end of the link 24 is fastened to the disk wheel 26 by a pin 24. The disk wheel 21 is provided with parallel flanges 21 21 which pass diametrically across it, the purpose of which is now described. I

31 is an arm having its one end squared to pass snugly between the flanges 21 21 said end being pivotally secured to the flanges by means of a vertically directed pin 32. Spiral springs 33 and 34 are interposed between the end of the arm and the face of the disk wheel to either side of the center of the wheel, such springs being held in a set position in any desired manner such as by grooves formed in the respective parts which receive the ends of the springs. According to this mounting the free end of the arm is capable of a swinging motion in a vertical direction when the shaft is turned and is also free-to be displaced laterally swinging on the pin 32. The arm is provided with arched bars 35 which form a cradle to receive the sheaves passing from the deck, it being understood that the deck is extended by a sheeting 11 which will direct the sheaves into the cradle when the cradle is in the horizontal receiving position.

36 is a lug passing vertically from the standard 16.

37 is a spiral spring secured to the upper end of the lug at one end and having its other end firmly fastened to the extending end of the arm 31. The spring is constructed so that when the arm is in either of its horizontal posit-ions there is a tendency for it to pass to the vertical position due to the action of the spring and consequently a natural tendency to remain in the vertical pom'tion such being the unextended position of the spring.

The.

passing forwardly;

' eeaei-i 3'8 and 39 are lugs passing upwardly and outwardly from one side of the arm adj oining the central bar 35 i '40 is an arched catch bar pivotally secured between the lugs 38 and 39, such bar being constructed so that one end 40 extends upwardly within the cradle so as to be throwndownwardly by the deposited sheaf.

41 and 42 are lugs passing upwardly from the bar and carrying slidably a trip rod 43 which is connected through a link 44 with the-lug 36. c l

45 is a spring abutting at one end the lug 42 and having the other end fastened/to the trio rod. The trip rod is adapted to pass over the end 40 of the catch bar when such end is passed downwardly by the sheaf.

46 and 47 are brackets secured to the platformat the end which adjoins the basket such brackets carrying a rotatable shaft 48 which has one end supplied with a disk wheel 49, said wheel being connected through a link 50 with the crank wheel 20 already referred to.

51 is a vertically directed deflecting bar having the upperend turned backwardly on itself at 51 to present an inclined face to receive and displace the arm 31 as later described. The rod has its lower end carried in any convenient form of cupdoearing located on the platform and has the body por* tion thereof mounted in a suitable bearing formed in a bracket 52 which extends upwardly from the platform.

53 is a gear wheel on the shaft 48 and 54 is a second gear wheel on the lower end of the rod, such latter gear wheels meshing the one with the other.

In connection with the parts which operate the arm 31 and the rod 51 it might be mentioned that the gears are constructed and the links laced so that for each half turn of the sha 't 18 the rod 51 is turned one-quarter turn. As shown in the drawings these parts have been connected and constructedso that the link 50 rotates the disk wheel 49 one revolution for each forward and backward swing ofthe arm 31 it being understood that the disk wheel 49 turns always in the same direction. The shaft 48 conse quently rotates always in the same direction and carries with ,it the gear 53 the motion of which rotates the rod 51. The gears 53 and 54 are proportioned so that for one revolution of the shaft 48 the rod 51 is turned one-half of a revolution.

To better understand the invention we will now describe its operation assuming the parts in the position shown and the clutch members in engagement, the binding machlne A sheaf passes over the deck 11 and sheeting 11 into the cradle. As the sheaf drops it engages with the upturned end 40 of the catch bar and throws the upper end 40 of I bar consequently in a set position so that it chine frame presenting a suitable platform is impossible for the sheaf to escape from the cradle when the arm is swinging to the opposite horizontal position. As' the armswings over the rod 51 is turned and assumes the position shown in dotted outline in Fig. 2, so that the bar is deflected to one side of the divider. The sheaf is released from the cradle just prior to the time it assumes the horizontal position over the basket as the trip rod is pulled backwardly by the action of the link 44 thereby releasing the catch bar. When the arm has resumed its original position the rod 51 has turned one-quarter turn in the same direction as formerly so that when the bar is again swung to the reeeptacle the end 51-of the rod is ina position which will deflect the bar to the opposite side of the divider to that already referred to. This swinging and shifting of the bar continues as along as the machine is in operation so that the shock is evenly built in the basket, the sheaves being delivered alternately to the opposite sides of the divider. When the basket is filled with sheaves the operatorstops the movement of the arm by throwing the clutch the basket being then dumped to deposit the shock on the ground.
